Answer:
0.38m/s
Explanation:
Given data
M1= 0.4kg
U1= 10m/s
M2= 70kg
U2= 0m/s
The system experiences an inelastic collision, the expression for inelastic collision is
M1U1+ M2U1= (M1+M2)V
Subsitute
0.4*10+ 70*0= (0.4+10)*V
4= 10.4V
4=10.4V
V= 4/10.4
V=0.38m/s
Hence the common velocity is 0.38m/s
Answer:
23932242.5 Pa
Explanation:
= Atmospheric pressure =
= Pressure of seawater
= Density of sea water =
h = Depth of shipwreck =
g = Acceleration due to gravity = 9.81 m/s²
The absolute pressure is given by
The absolute pressure at the depth of the shipwreck is 23932242.5 Pa
F_g=Gm_1m_2/r^2. mass and distance determines gravity.
Answer:
As a result of certain types of plate movement, you get different changes to the earth's surface.
Divergent plates (ones that move away from each other) you get mid ocean ridges as a result of sea floor spreading.
Convergent plate (ones that move towards one another) you get volcanoes and mountains.
Transformation plates (one that slide past one another) you get earthquakes and faults.
2 J / 4 C = 1/2 joule per coulomb.
That's 1/2 volt.
